Attempt to assign property

[doddsey_65]

I am getting the error

Attempt to assign property of non-object

 

when uploading my code to the server. Everything works fine locally however. The error is generated because i have an object $data.

I then assign a new property and value using $data->error = 'some error'; but my live server doesnt seem to like this.

Is this normal behaviour? is there

a workaround for this?

 

my localhost is running php 5.3 and the live server is using 5.2 if that helps.

Could you post your code here (within

or

tags).

sure but the object is generated via JSON so i will post the javascript object too.

 

JS object:

 

var data = {
            'post':
            [
                {subject        :    asf.getInput('subject')},
                {content        :    asf.getInput('post_content')},
                {forum_id        :    '{FORUM_ID}'},
                {topic_id        :    '{TOPIC_ID}'}
            ]
        }

 

and the php

$data = json_decode($_POST['data']);
        
add_post('topic',$data);

function add_post($method, $data)
{
    $db = db_pdo::$instance;
    
    $user = sessionsClass::$data;
    
    if(empty($data->post[0]->subject))
    {
        $data->post[0]->subject = 'No Subject';
    }
    
    if(empty($data->post[1]->content))
    {
        $data->error = 'You must supply a message body';
    }    

if($method == 'topic')
    {
        // sql for topic insertion
        $sql = "INSERT INTO ".TBL_PREFIX."topics
                (t_fid, 
                t_name, 
                t_poster, 
                t_time_posted,
                t_last_poster, 
                t_last_post_time)
                VALUES
                (:forum_id, 
                :subject, 
                :poster, 
                :time, 
                :last_poster, 
                :last_post_time)";
        
        // prepare the sql statement
        $sth = $db->prepare($sql);
        
        // execute the sql statement
        $sth->execute(array(
            ':forum_id'            => $data->post[2]->forum_id,
            ':subject'            => $data->post[0]->subject,
            ':poster'            => $user['u_username'],
            ':time'                => time(),
            ':last_poster'        => $user['u_username'],
            ':last_post_time'    => time()
            )
        )or die($db->printError($sql));
        
        if(empty($data->error))
        {
            $data->success = 'Your topic has been created';
        }
        
        echo json_encode($data);

 

* removed some code to shorten(just queries)

 

as you can see error and success dont appear in the original object so i add them, but the live server isnt liking this.
